Location and
Method
of
Checking
Check
that
bat
tery voltage
is
not
below
4.5V.
~love
slider and confirm
contact.
Check
if current
is
going to
the electromagnet
.
Check if
gap
between rubber
roller
and
pen
tip
is
0.6mm
in
the
pen·up mode.
Check
if
battery voltage is
below 4.SV.
Check
operation
of
the
actuator
for the
electro·
magnet
unit,
spring
fatigue,
deformation
,
etc.
Check that
rotary
holder
pen
is
directly above
the
specified
position
(print
position)
.
Check for
a
bend
in
the
ejection
lever
and
inspect
the
bearing
section.
Repair
Method
